Abstract

The invention discloses a double-cavity vacuum cooling machine. A left cavity and a right cavity are connected with a vacuum cooling system through an air suction pipeline, and air release valves and temperature probes are arranged on the cavities; an emptying valve is arranged between the left cavity and the right cavity, and cooling shelves are arranged in the cavities. The vacuum cooling system comprises a water catcher, a roots pump, a water ring vacuum pump and a vacuum electromagnetic valve, the roots pump is connected with the lower side of the water catcher, the water ring vacuum pump is connected with the right side of the roots pump, and the vacuum electromagnetic valve is connected with the upper side of the water ring vacuum pump. The vacuum cooling machine with the double cavities is designed, and theoretically, energy can be saved by 50% or above compared with that of a traditional single-cavity vacuum cooling machine.

Description

technical field [0001] The invention relates to the technical field of food storage, and more specifically relates to a double-chamber vacuum cooler. Background technique [0002] With the rapid development of society and the improvement of people's living standards, people have higher and higher requirements for food quality and safety. In the process of food production, the longer the cooked food is placed at 30°C-60°C, the faster the biological fermentation and bacterial reproduction will be, which will lead to accelerated food deterioration and decay, shortening the shelf life (shelf life) of the food. . The vacuum cooler can solve the problem that cooked food is easy to breed spoilage bacteria. Vacuum cooling technology is a cooling technology in which the water-containing material is rapidly cooled by water evaporation and heat transfer under the condition of a closed vacuum. The food in the vacuum cooling not only has a uniform temperature distribution, but also co...
